Description

Technical Field

[0001] This utility model relates to the field of switch panel technology, and more specifically, it relates to a locking device for wall switches. Background Technology

[0002] Wall switches, as core components for controlling indoor lighting and electrical appliance operation, are widely used in homes, offices, commercial spaces, and other locations. To prevent children from accidentally touching them or to prevent them from being switched on during operation, various wall switch locking devices have emerged on the market. Their core function is to lock the switch panel through a mechanical structure, restricting the pressing or flipping of the panel.

[0003] An existing locking device used in wall switches has been found to have the following issues during use:

[0004] 1. Existing locking devices mostly have a fixed locking position design, which can only lock the switch in a single state of "on" or "off", and cannot flexibly adjust the locking point according to actual needs, thus resulting in poor practicality.

[0005] 2. When not in use, the locking components of existing latching devices (such as blocks and pressure plates) are often directly exposed or protruding from the front of the switch panel, lacking effective storage or avoidance design. This affects the portability of normal use when the operator is operating the switch, resulting in poor practicality.

[0006] 3. The locking process of existing locking devices often relies on multiple sets of bolts for fixing or complex snap-fit ​​coordination: for example, some devices require screws to be turned one by one to press the stop block against the panel, or require multiple alignments of the snap-fit ​​to complete the locking, which greatly reduces the convenience of operation and thus results in poor practicality. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the problems existing in the prior art, this utility model provides a locking device for wall switches, so as to solve the technical problems mentioned in the background art, such as affecting the normal operation of the switch when idle, the single locking state, the inability to adapt to the needs of multiple scenarios, and the cumbersome and inefficient locking operation.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a locking device for a wall switch, comprising a frame, a panel body disposed inside the frame, an annular plate disposed outside the frame, a positioning component disposed on the top of the annular plate, sliding grooves disposed on both sides of the front end of the annular plate, a first slider slidably disposed in each of the two sets of annular plate sliding grooves, threaded holes disposed at the top and bottom of the annular plate sliding grooves, threaded holes disposed in each of the two sets of first sliders, first screws disposed in each of the two sets of first sliders, the outer sides of the two sets of first screws being threadedly connected to the first sliders and the corresponding threaded holes of the annular plate, a support plate disposed at the front end of each of the two sets of first sliders, a connecting plate hinged to the top of the front end of each of the two sets of support plates, a baffle disposed at the bottom of the front end of each of the two sets of support plates, the top of the two sets of baffles being in close contact with the bottom of the connecting plate, an mounting block disposed at the front end of each of the two sets of connecting plates, an adjustment mechanism disposed at the rear end of the mounting block, a pressure block disposed at the rear end of the mounting block through the adjustment mechanism, the rear end of the pressure block being in close contact with the top of the front end of the panel body.

[0011] The present invention is further configured such that the adjusting mechanism includes two sets of threaded cylinders, two sets of connecting screws, and two sets of connecting blocks. Each mounting block has a working cavity, with a pre-drilled hole at its front end. A rotating rod is rotatably mounted within the pre-drilled hole. The rear end of the rotating rod is rotatably connected to the rear end of the working cavity. A mounting ring is rotatably mounted on the outer side of the rotating rod, and a driving bevel gear is mounted on the rear end of the outer side of the rotating rod. The outer sides of both sets of connecting blocks slide tightly against the inner side of the working cavity. Connecting screws are mounted at opposite ends of both sets of connecting blocks. Each opposite end of each set of connecting screws is threadedly connected to one end of a set of threaded cylinders. The other ends of both sets of threaded cylinders are rotatably connected to one end of the mounting ring. Driven bevel gears are mounted on the outer sides of both sets of threaded cylinders, and both sets of driven bevel gears mesh with the driving bevel gear. The rear ends of the working cavity are provided with... The device features sliding holes, within which two sets of second sliders are slidably mounted. The front ends of both sets of second sliders are connected to the rear ends of the connecting block, and the rear ends of both sets of second sliders are equipped with hinge components, which are then hinged to the front ends of the pressure block. Power transmission is achieved through a combination of bevel gear transmission and threaded transmission. Simply rotating the second handle drives the pressure block to move linearly, replacing the tedious operation of tightening multiple bolts one by one in traditional locking devices. This significantly improves the efficiency of locking and unlocking, especially in emergency situations (such as when quick unlocking is required), greatly reducing operation time. Furthermore, the threaded engagement between the threaded cylinder and the connecting screw has a self-locking function, ensuring stability of the locked state even under vibration. The overall structure is compact, with efficient power transmission, balancing ease of operation and locking reliability.

[0012] The present invention is further configured such that the hinge assembly includes a hinge seat, a support rod, and a sliding plate. Each of the two sets of second sliders has a sliding plate at its rear end, and each of the two sets of sliding plates has two sets of hinge seats at its rear end. The rear ends of the two sets of sliding plates are respectively hinged to the front end of the support rod via two sets of hinge seats. The front end of the pressure block has four sets of hinge seats evenly distributed, and the front end of the pressure block is hinged to the rear end of the support rod via four sets of hinge seats. Through the cooperation of multiple sets of hinge seats and the support rod, the linear motion of the second slider is smoothly transmitted to the pressure block, solving the problem of pressure block tilting that may occur with rigid connections. This ensures that the pressure block fully fits the panel body, improving the reliability of locking. Furthermore, the multi-point support design disperses the pressure of the pressure block on the panel, thus enhancing practicality.

[0013] The present invention is further configured such that the positioning component includes a mounting plate, the bottom of the mounting plate is connected to the top of an annular plate, a groove is provided at the front end of the mounting plate, a second screw is rotatably disposed in the groove of the mounting plate, a third slider is threadedly connected to the outer side of the second screw, the third slider is slidably connected to the groove of the mounting plate, a clamping plate is provided at the front end of the third slider, a positioning block is provided at the bottom of the clamping plate, and a positioning groove is provided at the top front end of the mounting block; this achieves stable storage of the mounting block when the device is idle, solves the problem of components protruding and interfering with the normal operation of the panel when the traditional locking device is idle, and improves the convenience of using the switch.

[0014] The present invention is further configured such that each of the two sets of first screws is provided with a first handle at one end; in accordance with the principles of ergonomics, by increasing the distance between the point of force application and the center of rotation, the force required for operation is reduced, thus enhancing practicality.

[0015] The present invention is further provided with a second handle at the front end of the rotating rod; in accordance with ergonomic principles, by increasing the distance between the point of force application and the center of rotation, the force required for operation is reduced, thus enhancing practicality.

[0016] The present invention is further configured such that the top of the second screw passes through the mounting plate groove and is provided with a third handle; in accordance with ergonomic principles, by increasing the distance between the force application point and the rotation center, the force required for operation is reduced, thus enhancing practicality.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a locking device for wall switches, which has the following advantages:

[0019] 1. The horizontal position of the mounting block is adjusted by the first slider, the slide groove, and the first screw. Combined with the rotational adaptability of the connecting plate, it breaks the limitation of the fixed locking position of traditional locking devices. The contact point between the pressure block and the panel body can be flexibly adjusted according to actual needs to achieve locking of the panel in multiple states such as "open" and "closed". It adapts to the usage needs of different scenarios (such as preventing children from accidentally turning off important equipment or fixing specific working states). Furthermore, the cooperation between the first screw and the threaded hole not only allows for precise position adjustment, but also forms a self-locking mechanism after adjustment, preventing the mounting block from shifting during the locking process and ensuring locking stability. At the same time, the baffle limits the angle of the connecting plate (only 90 degrees of rotation and remaining perpendicular to the frame), ensuring that the mounting block remains horizontal in any adjustment position, so that the pressure block is always in parallel contact with the panel body. This avoids excessive local force or locking failure due to tilting, thus improving the stability of the locking.

[0020] 2. Power transmission is achieved through a combination of bevel gear transmission and threaded transmission. Simply rotating the second handle drives the pressure block to move linearly, replacing the tedious operation of tightening multiple sets of bolts one by one in traditional locking devices. This significantly improves the efficiency of locking and unlocking, especially in emergency situations (such as when quick unlocking is required), which can significantly reduce operation time. Furthermore, the threaded engagement between the threaded cylinder and the connecting screw has a self-locking function. Even if subjected to vibration after locking, it will not loosen on its own, ensuring the stability of the locked state. The overall structure is compact, the power transmission is efficient, and it balances ease of operation with locking reliability.

[0021] 3. It enables stable storage of the mounting block when the device is not in use, solving the problem of protruding parts and interfering with the normal operation of the panel when the traditional locking device is not in use, thus improving the convenience of using the switch.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] Please see Figure 1-5 A locking device for a wall switch includes a frame 1, a panel body 2 inside the frame 1, an annular plate 3 outside the frame 1, a positioning component on the top of the annular plate 3, sliding grooves on both sides of the front end of the annular plate 3, and first sliders 4 slidably disposed in the sliding grooves of the two sets of annular plate 3. Threaded holes are provided at the top and bottom of the sliding grooves of the annular plate 3, and threaded holes are provided in the two sets of first sliders 4. First screws 5 are provided in the two sets of first sliders 4, and the outer sides of the two sets of first screws 5 are threadedly connected to the first sliders 4 and the corresponding threaded holes of the annular plate 3. Support plates 6 are provided at the front end of the two sets of first sliders 4, and connecting plates 7 are hinged to the top of the front end of the two sets of support plates 6. Baffles 8 are provided at the bottom of the front end of the two sets of support plates 6, and the top of the two sets of baffles 8 and the bottom of the connecting plates 7 are in close contact. Mounting blocks 9 are provided at the front end of the two sets of connecting plates 7, and an adjustment mechanism is provided at the rear end of the mounting blocks 9. A pressure block 10 is provided at the rear end of the mounting blocks 9 through the adjustment mechanism, and the rear end of the pressure block 10 is in close contact with the top of the front end of the panel body 2.

[0032] In this embodiment, when it is necessary to lock the panel body 2, the operator first adjusts the positioning component to cancel the positioning of the mounting block 9. Then, the position of the first slider 4 is adjusted by the sliding grooves on both sides of the front end of the annular plate 3. By rotating the first screw 5, the first screw 5 is disengaged from the threaded hole of the first slider 4. Then, the first slider 4 is driven to slide along the sliding groove, thereby driving the front end support plate 6 to move horizontally. This adjusts the relative position of the mounting block 9 and the panel body 2. After moving to the corresponding position, the pressure block 10 is driven to move backward by the adjustment mechanism so that the rear end of the pressure block 10 is pressed tightly against the top of the front end of the panel body 2, thus completing the locking.

[0033] More specifically, when it is necessary to lock the panel body 2, the operator rotates the second screw 23, causing the third slider 24 to start sliding the clamping plate 25 until the clamping plate 25 drives the positioning block 26 and the positioning groove 27 to disengage. Then, the mounting block 9 is flipped over, causing the mounting block 9 to rotate through the connecting plate 7 until the bottom of the connecting plate 7 and the top of the baffle 8 are tightly attached, and then the locking state is achieved.

[0034] Please see Figure 1 and Figure 4 As one embodiment of the adjustment mechanism: the adjustment mechanism includes two sets of threaded cylinders 11, two sets of connecting screws 12, and two sets of connecting blocks 13. The mounting block 9 is provided with a working cavity 14. A pre-drilled hole is provided at the front end of the working cavity 14. A rotating rod 31 is rotatably mounted within the pre-drilled hole of the working cavity 14. The rear end of the rotating rod 31 is rotatably connected to the rear end of the working cavity 14. A mounting ring 15 is rotatably mounted on the outer side of the rotating rod 31, and a drive bevel gear 16 is provided at the rear end of the outer side of the rotating rod 31. The outer sides of both sets of connecting blocks 13 are slidably pressed against the inner side of the working cavity 14. Connecting screws 12 are provided at opposite ends of the two sets of connecting blocks 13. One end of each connecting screw 12 is threaded to one end of a set of threaded cylinders 11. The other ends of the two sets of threaded cylinders 11 are rotatably connected to one end of the mounting ring 15. Both sets of threaded cylinders 11 are provided with driven bevel gears 17 on their outer sides, and both sets of driven bevel gears 17 are meshed with driving bevel gears 16. Both sides of the rear end of the working chamber 14 are provided with sliding holes. The two sets of working chambers 14 are slidably provided with second sliders 18 in the sliding holes. The front ends of the two sets of second sliders 18 are connected to the rear end of the connecting block 13, and the rear ends of the two sets of second sliders 18 are provided with hinge components. The rear ends of the two sets of second sliders 18 are hinged to the front end of the pressure block 10 through the hinge components.

[0035] Specifically, when the panel needs to be locked, the second handle 29 at the front end of the rotating rod 31 is rotated, causing the rotating rod 31 to rotate within the working cavity 14 of the mounting block 9. The driving bevel gear 16 at the outer rear end of the rotating rod 31 rotates synchronously, driving the two sets of driven bevel gears 17 meshing with it to rotate. The two sets of threaded cylinders 11 begin to rotate, and the connecting screw 12 drives the connecting block 13 to move axially along the working cavity 14. The second slider 18 slides synchronously with the connecting block 13, and pushes the pressure block 10 to move backward through the hinge assembly at the rear end until it is tightly pressed against the panel body 2 to complete the locking. When unlocking, the second handle 29 is rotated in the opposite direction, and the driving bevel gear 16 drives the driven bevel gear 17 to rotate in the opposite direction. The threaded cylinder 11 drives the connecting screw 12 and the connecting block 13 to move in the opposite direction. The pressure block 10 is driven forward and disengaged from the panel body 2 by the hinge assembly.

[0036] Please refer to Figures 2-4 As a further embodiment of the hinge assembly: the hinge assembly includes a hinge seat 19, a support rod 20 and a slide plate 21. The rear ends of the two sets of second sliders 18 are each provided with a slide plate 21. The rear ends of the two sets of slide plates 21 are each provided with two sets of hinge seats 19. The rear ends of the two sets of slide plates 21 are respectively hinged to the front ends of the support rod 20 through the two sets of hinge seats 19. The front ends of the pressure block 10 are evenly provided with four sets of hinge seats 19. The front ends of the pressure block 10 are hinged to the rear ends of the support rod 20 through the four sets of hinge seats 19.

[0037] Specifically, when the second slider 18 slides in the sliding hole of the working cavity 14, the slide plate 21 at its front end moves synchronously. The two sets of hinge seats 19 at the rear end of the slide plate 21 drive the front end of the support rod 20 to rotate. The rear end of the support rod 20 is connected to the pressure block 10 through the four sets of hinge seats 19 at the front end of the pressure block 10, converting the linear motion of the slide plate 21 into the smooth sliding of the pressure block 10 until it is tightly attached to the panel body 2 and locked.

[0038] In summary, during the use or operation of the overall equipment:

[0039] When it is necessary to lock the panel body 2, the operator rotates the second screw 23 using the third handle 30, causing the third slider 24 to slide along the clamping plate 25 until the clamping plate 25 disengages the positioning block 26 and the positioning groove 27. Then, the mounting block 9 is flipped over, causing it to rotate along the connecting plate 7 until the bottom of the connecting plate 7 and the top of the baffle 8 are in close contact. The first screw 5 is then rotated using the first handle 28, disengaging it from the threaded hole of the first slider 4. The position of the first slider 4 is then adjusted using the sliding grooves on both sides of the front end of the annular plate 3, and the first slider 4 is driven to slide along the sliding grooves, thereby causing the front support plate 6 to move horizontally, thus adjusting the relative position of the mounting block 9 and the panel body 2. After moving to the corresponding position, rotate the second handle 29 at the front end of the rotating rod 31, causing the rotating rod 31 to rotate within the working cavity 14 of the mounting block 9. The active bevel gear 16 at the outer rear end of the rotating rod 31 rotates synchronously, driving the two sets of driven bevel gears 17 meshing with it to rotate. The two sets of threaded cylinders 11 begin to rotate. The connecting screw 12 drives the connecting block 13 to move axially along the working cavity 14. The second slider 18 slides synchronously with the connecting block 13. The two sets of hinge seats 19 at the rear end of the slide plate 21 drive the front end of the support rod 20 to rotate. The rear end of the support rod 20 is connected to the pressure block 10 through the four sets of hinge seats 19 at the front end of the pressure block 10, converting the linear motion of the slide plate 21 into the smooth sliding of the pressure block 10 until it is tightly pressed against the panel body 2 and locked.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
